[Dovecot] Internal Error - Cannot select inbox (solved) though where are the error messages logged

[Eric Beda]

Hi,

through various trial and errors i've found the solution to my problem, i
disabled the mbox_min_index_size, it was set to 200 ( i think i read in
some  tutorial that this will increase performance)

#mbox_min_index_size = 200

After disabling it the errors stopped though i still have a niggling issue
still unresolved

Where do the error messages go ??? i read through the debuging tutorial,,
the dovecot --log-error command doesn't work,,, or maybe i am not
executing it properly

# dovecot --log-error
Usage: dovecot [-F] [-c <config file>] [-p] [-n] [-a]
       [--exec-mail <protocol>] [--version] [--build-options]
Fatal: Unknown argument: --log-error

That is what i get after command execution, how do i find out where the
error messages are logged ???
